improved indentation and whitespace for markdown code blocks
All code blocks in markdown have been intended by at least 4 spaces. We add `--tab-stop=8` to all `pandoc(1)` executions in order to set a better tab stop indentation, especially for tab intended code blocks. Changed `bin/pandoc-wrapper.sh` VERSION from "1.5.3 2024-03-26" to "1.6 2024-03-31". Fixed `1991/brnstnd/sorta.README.md` so that the sorta code is code blocks. Removed unneeded paragraph group in copyright in `inc/footer.default.html`. Fixed excess whitespace after list Author on entry `index.html` page. Changed `bin/output-index-author.sh` VERSION from "1.5.2 2024-03-26" to "1.6 2024-03-31". Performed `make www` to perform the above and test under macOS. TODO: Fix the problem of the initial line of code being extra intended. TODO: Fix excess whitespace around code that is inline.

<p>NOTE: we have provided a script to perform the below procedure which we include
|
||||
for the interested. See the <a href="#try">try</a> section if you just want to play.</p>
|
||||
<p>Make and then run as follows:</p>
|
||||
<div class="sourceCode" id="cb3"><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb3-1"><a href="#cb3-1" aria-hidden="true" tabindex="-1"></a><span class="ex">./westley</span> <span class="pp">[</span><span class="ss">move_location</span><span class="pp">]</span> <span class="kw">|</span> <span class="fu">tee</span> nextmove.c</span></code></pre></div>

|

<p>where the <code>move_location</code> is a digit from 1 to 9 that represents
|
||||
a move on a tic-tac-toe board:</p>
|
||||
<pre><code>1 2 3
|
||||
4 5 6
|

7 8 9</code></pre>
|
||||
<pre><code> 1 2 3
|
||||
4 5 6
|
||||
7 8 9</code></pre>
|
||||
<p>If you omit <code>move_location</code>, then the computer moves first. For your
|
||||
next move, recompile <code>nextmove.c</code> and play it again:</p>
|
||||
<div class="sourceCode" id="cb5"><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb5-1"><a href="#cb5-1" aria-hidden="true" tabindex="-1"></a><span class="fu">make</span> nextmove</span>

<h2 id="try">Try:</h2>
|

<p>We have provided the shell script, <a href="ttt.sh">ttt</a>, to make it easier to play the

game:</p>

|
||||
<p>The shell script determines when the game is over, and automatically replaces
|
||||
<code>merlyn.c</code> (copied from <a href="westley.c">westley.c</a> with an improved version after a
|
||||
loss). The <a href="ttt.sh">ttt</a> script has two other modes:</p>
|
||||
<div class="sourceCode" id="cb7"><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb7-1"><a href="#cb7-1" aria-hidden="true" tabindex="-1"></a><span class="ex">./ttt</span> quitgame <span class="co"># cancel any game in progress, revert to merlyn.c</span></span>
|
||||
<span id="cb7-2"><a href="#cb7-2" aria-hidden="true" tabindex="-1"></a><span class="ex">./ttt</span> clobber <span class="co"># remove all game files, revert to original source</span></span></code></pre></div>
|

<div class="sourceCode" id="cb7"><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb7-1"><a href="#cb7-1" aria-hidden="true" tabindex="-1"></a> <span class="ex">./ttt</span> quitgame <span class="co"># cancel any game in progress, revert to merlyn.c</span></span>

<span id="cb7-2"><a href="#cb7-2" aria-hidden="true" tabindex="-1"></a> <span class="ex">./ttt</span> clobber <span class="co"># remove all game files, revert to original source</span></span></code></pre></div>
|
||||
<p>For example here is a potentially losing game:</p>
|
||||
<div class="sourceCode" id="cb8"><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb8-1"><a href="#cb8-1" aria-hidden="true" tabindex="-1"></a><span class="ex">./ttt</span> 1</span>
|

<span id="cb8-2"><a href="#cb8-2" aria-hidden="true" tabindex="-1"></a><span class="ex">./ttt</span> 4</span>
|
||||
<span id="cb8-3"><a href="#cb8-3" aria-hidden="true" tabindex="-1"></a><span class="ex">./ttt</span> 6</span></code></pre></div>
|
||||
<div class="sourceCode" id="cb8"><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb8-1"><a href="#cb8-1" aria-hidden="true" tabindex="-1"></a> <span class="ex">./ttt</span> 1</span>

<span id="cb8-2"><a href="#cb8-2" aria-hidden="true" tabindex="-1"></a> <span class="ex">./ttt</span> 4</span>

<span id="cb8-3"><a href="#cb8-3" aria-hidden="true" tabindex="-1"></a> <span class="ex">./ttt</span> 6</span></code></pre></div>
